SINGLE CARBURETTOR ENGINE—Short Engine—U.S.A.
REBUILT ENGINE UNITS
The Roadster Factory offers its own factory rebuilt engines and cylinder heads (see p. 6), and we believe thatthese units are the best solution available to most enthusiasts who need an engine overhaul. At TRF, we know everypart of the Spitfire 1500 engine intimately, and rebuild them to exacting standards
When rebuilding an engine, we start by disassembling the old unit and sandblasting the outside surfaces free of allpaint, rust, and other dirt. We then hot tank the blocks and have all of the cylinders rebored on every engine. We thenhand-clean everything, scrubbing with brushes and using lots of water rinses and compressed air to thoroughly cleanall passages. Crankshafts are magnafluxed for cracks, checked for straightness, and reground, nearly always to just.010 inch undersize. New bearings and thrust washers are always fitted, of course, and great care is taken to insurethat all tolerances are perfect. We fit new pistons and rings every time, and all connecting rods are checked forstraightness and rebushed. Reground camshafts are fitted, and timing gears are replaced or reused, depending uponcondition. We always include new timing chains, tensioners and valve tappets, and we fit new oil pump assemblies.Our “short engines” are rebuilt complete with oil pans, timing covers, and new front and rear seals. When everything isassembled with new gaskets, holes are blanked off, and the engine is spray painted with a durable black enamel.Short engines do not include cylinder heads, flywheels, front pulleys, or any bolt-on accessories.
If customers wish to have their own engines rebuilt rather than exchanging them for rebuilt units in order to keeporiginal serial numbers or for any other reason, we are able to accommodate them with a turn-around time of aroundsix to eight weeks.
Quality is the watchword throughout our engine rebuilding process, and we guarantee our units to be free fromdefects in material or workmanship for six months or six thousand miles from the date of purchase, provided that theunit is properly serviced and not used in competition. Please be sure to fill the unit with oil upon installation!

SINGLE CARBURETTOR ENGINE—Rebuilt Cylinder Head.
THE ROADSTER FACTORy’S REBUILTCyLINDER HEADS
We rebuild our own cylinder heads at The Roadster Factory, following the same rigidprocedures we do for our rebuilt engine blocks. Cylinder heads are first stripped and thoroughlycleaned. New valve guides are then fitted, and they are given a precision valve job. New valve springsare fitted every time, of course, along with new valves, although we also offer heads which have beenrebuilt with good used valves, when available, at a reduced price. The following rebuilt cylinder headsfor Spitfire 1500 are listed with the corresponding original cylinder head part number in parentheses toaid the customer in choosing the correct component.
For more information about engine rebuilding, please call Tom Spadafora of C.A.R.Components at (814) 446-4423 x 3029 or email him at [email protected]. The Car Componentsweb site can be accessed through the menu link on The Roadster Factory website www.the-roadster-factory.com.

SINGLE CARBURETTOR ENGINE—Cast Alloy Valve Covers
Some of the early Triumphs were equipped with cast aluminum valve covers as optionalequipment. There are a number of advantages to cast aluminum valve covers over the pressedsteel valve covers fitted to most models as original equipment. The quiet valve noise, they do notbend when the securing nuts are tightened, and they are very attractive. Although the castaluminum covers listed here are not original equipment, they do include all of the advantagesdescribed, and they make a striking addition to your Spitfire’s engine compartment.

SINGLE CARBURETTOR ENGINE—Piston Assembly—U.S.A. Federaland California Models
Pistons were available in two types: low compression (dish top) and hight compression (flattop). The low compression pistons were fitted to U.S. Federal models up to engine no.FM40000UE and after FM80000UE, and to all California models. High compression pistons werefitted to U.S. Federal models between engine no. FM40000UE and FM80000UE. Lowcompression pistons create a compression ration of7.5:1. High compression pistons create acompression ratio of 9:1. Parts numbers are as follows:
HIGH COMPRESSION PISTONSPiston (standard size) CBP20139/STDPiston (010 in. oversize) CBP20139/010Piston (020 in. oversize) CBP20139/020Piston (030 in. oversize) CBP20139/030Piston (040 in. oversize) CBP20139/040
Pistons are sold in sets (of 4) only.
Piston rings are not suppliedseparately for one piston
Piston rings are available in sets(enough for one car) as follows:
Std size BHM1175

SINGLE CARBURETTOR ENGINE—Zenith Stromberg Carburettor PartNumbers
For several reasons, we have chosen to double-list the carburettors, giving the British Leyland partnumbers on the previous pages, and the Zenith Stromberg part numbers on this page. Some parts will belisted twice, once under a British Leyland number and once under a Zenith Stromberg number. We obtainthese parts from whomever is the best source, and you will be able to find the current price for anyparticular part by looking up either part number in our general price list which should always accompanythis catalogue.
Note: You can always tell which carburettor you have on your car, because the Zenith Stromberg partnumber of the carburettor assembly will be stamped on your carb.

SINGLE CARBURETTOR ENGINE—Carburettor Tuning Tools—Colortune, Unisyn, Mixture Adjusting
Any Triumph enthusiast, who has been around for any length of time, has met theold guys who tune their carbs by listening to and comparing the notes of the hissesthe carbs make when they draw air through a piece of rubber tubing. These sameguys always have nice even exhaust notes, idles at six or seven R.P.M.’s and havenice grey deposits on the insides of their tailpipes. They are smart, knowledgeableand experienced. They’ve been around for a long time, and they’ve learned thecraft. For those of us whose ears are not yet experienced enough to tell whether amixture is too rich or too lean by raising a carburettor piston or who missed schoolthe day the teacher talked about air hissing through rubber hoses, there is still helpin the form of items like Unisyn air flow meters and the Colortune system foraccurately determining what kind of air/fuel mixture is being sucked into ourengines.
Part No. DescriptionGUCT500 Colortune Tune-up Kit (everything you need to set your
carburettor mixture by the Colortune method.)CAT2 Unisyn Air Flow Meter (Replaces the rubber tube with a
simple air flow meter that doesn’t require an experienced ear to accurately synchronize multiple carbs, if you happen to have a dual carb set-up, such as Webers, on your Spitfire 1500.)

Weber carbs have a mystique all their own. They have been run on the most successful high-performance engines for a generation or more, and their quality is undeniable. The results that weat TRF received from fitting a set to our TR250 rallye car confirmed this point for us.
The biggest advantage of buying a Weber kit from The Roadster Factory over buying it fromanyone else is that we offer technical support to help you to get the carbs on and in properadjustment.* Call our Technical Research Department at (814) 446-4491 for assistance inchoosing the proper Weber carburettor kit for your car.
